Dab tsi yog 254 smo stainless hlau?
254 smo yog aSuper Austenitic Stainless Hlau(UN tsis muaj S31254) muaj lub zog siab thiab ua kom muaj zog heev rau pitting corrosion, ua rau nws tshwj xeeb tshaj yog tsim nyog rau chloride ib puag ncig xws li dej hiav txwv. Nws cov ntsiab lus siab ntawm Molybdenum, npib tsib xee, cov pa roj ntsha ua rau nws muaj kev lag luam ruaj khov thiab siv tau rau hauv kev lag luam xws li naval, tshuaj lom neeg thiab ntawv.
SMO 254 cov khoom sib npaug nrog?

Dab tsi yog qhov sib txawv ntawm SMO 254 thiab SS316?
SMO 254 yog aSuper Austenitic Stainless Hlaunrog ntau dua molybdenum thiab cov ntsiab lus nitrogen, uas ua rau nwssiab dua SS316Hauv corrosion tsis kam (tshwj xeeb yog nyob rau hauv ib cheeb tsam nrog cov chloride cov ntsiab lus), neeg siv tshuab tsis kam thiab kev ua haujlwm ntawm qhov kub. SS316 yog ib qho ntau thiab pheej yig dua cov hlauustenitic stainless hlau, tab sis tsis muaj cov neeg xav tau xws li dej hiav txwv lossis tshuaj lom neeg.
